BIRD-CAGE.

SPECIFICATION forming part of Letters Patent No. 311,848, dated February 3 1885.

Application filed January 5, 1F84. (N0 model.)

To (ZZZ whom it may concern.- Be it known that I, JOHN PUTNAM, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and Improved Bird-Cage, of which the following is a full, clear, and exact description.

The object of my invention is to provide a certain new and useful improvement in birdcages, whereby the cleaning of the cage is facilitated and the appearance of the cage is improved.

The inventionconsists in the peculiar construction and arrangement of parts, as hereafter fully described, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a plan view of the bottom plate of my improved bird-cage. Fig. 2 is alongitudinal sectional elevation ofthe same on the line a; so, Fig. 1. Fig. 3 is a cross-sectional elevation of the same on the line 3 Fig. 1.

The bottom plate, A, of the bird cage is made of glass, and is provided with an upwardly-inclined rim, B, which projects beyond the base of the bird-cage frame. The plate Ais provided at two opposite sides with slots 0, through which locking-pins D, provided with heads D D", are passed. The pins Dare held to slide in apertures of the base flange or rim E of the bird-cage frame I, and are held raised by springs a, secured to said flange or rim E and engaging the heads D of the pins. The bird-cage frame I is secured to the bottom plate, A, by placing it on the said bottom plate, depressing the pins against the action of the springs to force them through the slots of the said bottom plate, and then giving them a quarter-turn, the springs, upon the release of pressure on the pins, forcing the same upward and firmly locking the cage-frame to the bottom plate. To remove the cage-frame from the bottom plate, it is only necessary to depress the pins and give them a quarter-turn to cause their lower heads, D to register with the slots 0 of the bottom plate, when the cage-frame can be taken off. Cups F for feed or water are formed on the rim of the bottom plate, or the said cups can be formed as wicket-s for receiving cups G for feed or water. A tubular projection, H, may be formed in. the middle of the bottom plate, which tubular projection is to receive a butt-on or head formed on the lower endofa rod or wire, by which the bot tom plate is suspended from the bird-cage frame, or the said tubular projection can re- Having thus described my invention, I claim as new and desire to secure by Letters Patent-- 1. The bird-cage bottom plate, A, made of glass, and provided with the feed-cups F and openings 0, the said l'ced'cup being integral with the bottom plate, substantially as herein shown and described.

2. The combination,with a bird-cage frame, I, having bottom rim, E, and thebottom plate, A, having slots 0, of the spring-pressed pins D, fitting loosely in apertures ot' the said bottom rim, and provided with the heads D D", substantially as herein shown and described.

3. The bird-cage bottom plate, A, made of glass, and provided with the openings 0, the feed-cups F, and the central tubular projection, H, substantially as herein shown and described.
